Abstract:
Objective: To explore the research method suitable for the component compatibility and optimization design of Chinese materia medica (CMM) by taking the blood pressure-lowering effect of the effective components in Ramulus Uncariae cum Uncie total alkaloids (RUCUTA) and Semen Raphani total alkaloids (SRTA) as the research objects. Methods: According to the procedure of "orthogonal design-evaluation on drug effect-partial least-squares regression (PLSR)", using contractive pressure as index, the ratio of RUCUTA and SRTA was optimized by orthogonal design method. The data were analyzed by range analysis, variance analysis, multiple regression analysis, and PLSR analysis. Results: According to the result of the data analysis and considering the economic costs, the optimal ratio of the two components was 25 μg/g RUCUTA and 30 μg/g SRTA. Conclusion: The compatibility of RUCUTA and SRTA could effectively reduce blood pressure. The orthogonal design method combined with PLSR could eliminate the interaction among the various factors and be suitable for the component compatibility in CMM and optimization design.
